A rectangle has sides measuring (6x + 4) units and (2x + 11) units. Part A: What is the expression that represents the area of the rectangle? Show your work to receive full credit. (4 points) Part B: What are the degree and classification of the expression obtained in Part A? (3 points) Part C: How does Part A demonstrate the closure property for polynomials? (3 points)

Do you know foil? For A multiply \((6x+4)(2x+11)\)

12x^2+74x+44 is what i got
anonymous
  • anonymous
that's the answer for A. For b the highest exponent is 2, so it's a quadratic
anonymous
  • anonymous
so the answer for b is quadratic

yes

can you help with c also

I never really know what they want for those. I know that polynomial are closed under multiplication, so they might just be to do the reverse \((2x+11)(6x+4)\) and show that you get the same answer from A.
